摘要： The invention is an on-axis optical projection system that displays an image on a projection surface. The optical projection system includes a light source and a reflective LCD microdisplay that modifies light from the light source to form a desired image. The LCD microdisplay reflects light toward the projection surface. A mirror reflects light from the light source in a first optical path toward the LCD microdisplay. The mirror does not affect the polarization orientation of the light reflected thereupon. A plurality of lenses are positioned within the system to focus and direct light along the first optical path and along a second optical path from the microdisplay to the projection surface. The first optical path is substantially opposite in direction to the second optical path. The plurality of lenses includes a dual-purpose lens that simultaneously transmits light along both the first optical path and the second optical path.

摘要： A contact planarization apparatus includes a lower membrane assembly, an upper membrane assembly, a differential pressure assembly, and a curing or reflowing assembly. The lower membrane assembly supports a substrate to be planarized and biases it toward the upper membrane assembly under the influence of the pressure differential assembly. The upper membrane assembly planarizes the coating on the substrate under the influence of the differential pressure assembly and includes a flexible sheet which is supported above the substrate stage and below the curing or reflowing assembly via a vacuum force applied by the differential pressure assembly. The differential pressure assembly moves the lower and upper membrane assemblies relative to one another to planarize the coating on the substrate entirely through the application of vacuum and pressure forces. The differential pressure assembly includes atop pressure chamber positioned above the upper face of the upper sheet, a bottom pressure chamber positioned below the lower face of the lower sheet, and a central pressure chamber positioned generally between the lower face of the upper sheet and the upper face of the lower sheet.

摘要： An illumination system is disclosed, which includes a first light source and a second light source configured to emit light when the first light source is not emitting light. A polarizing element accepts light from the first and second light sources. The polarizing element emits, along a light path, light from the first light source with a first polarization orientation. The polarizing element emits, along the light path, light from the second light source with a second polarization orientation. A homogenizing element receives and homogenizes polarized light from the polarizing element. A polarization rotator receives light from the homogenizing element. The polarization rotator selectively rotates one of the first and second polarization orientations to ensure light emitted therefrom maintains a constant polarization orientation.

摘要： Drive apparatus for driving an endless moving conveyor belt for a power turn to change the direction of movement of articles in a transfer conveying system wherein the plurality of rolls at each end of the power turn over which the endless conveyor belt passes have a diameter less than about one inch. An endless chain is attached to the endless moving conveyor belt for movement therewith. A drive shaft is provided adjacent to each end of the power turn and has a drive roll having a tapered outer surface and a drive sprocket mounted thereon for rotation therewith. A snub roll shaft is provided adjacent to each end of the power turn and has a snub roll integral with the snub roll drive shaft and having a tapered outer surface and a snub roll sprocket mounted on the drive roll snub shaft for rotation therewith. An idler sprocket is mounted on the outer side wall adjacent to each end of the power turn. The endless moving conveyor belt is trained around the power turn so that at one end portion it moves first over the outer surfaces of the plurality of the rolls, then over a portion of the lower half of a drive roll's outer surface and then over a portion of the upper half of the snub roll's outer surface to provide a frictional driving force. At the other end portion, the movement is in a reverse order. The endless chain is trained around the power turn so that at one end it moves first over the idler sprocket, then over a portion of the lower half of the drive sprocket and then over a portion of the upper half of the snub roll sprocket to provide a positive driving force. At the other end, the movement is in a reverse order.
